Not a long term solution, obviously..but you could send a few and hear how the process improves, or not, the sound of a few of your disks to help you decide what it's worth to you.
Fiesta75, thanks for the link. Amazon used to have that machine at a similar price, but they sold out. Now I only see it for $325 or more, most places.
